Redundancy available in digital media makes it possible to hide messages within various digital carriers like image, audio. Steganography is useful for secret communication. If images are taken as carrier for steganography any information either image, audio can be embedded into that image. But as images are frequently compressed before transmission or storage, information hiding in a compressed data format should be a better choice. JPEG2000 is latest image coding standard which uses embedded block coding truncation (EBCOT). It exhibits excellent compression performance with high complexity. ...
